Mads Mikkelsen is playing the main villain in Marvel’s new superhero movie, Doctor Strange, which stars Benedict Cumberbatch as the titular surgeon-turned-sorcerer.

Marvel Studios president and Doctor Strange producer Kevin Feige elaborates further. “We will take audiences through sort of a guide to the multiverse, other dimensions, and there are amazing things out there — wonders that are going to be hopefully visually extremely interesting and unique to this movie,” he says. “But there are also very scary things in these other dimensions.” According to Feige, is the job of sorcerers like Strange and The Ancient One, played by Tilda Swinton, to protect humanity from such “scary things.”

Although Broussard and Feige are happy to talk about the nature of Mikkelsen’s role, they are not, at present, revealing the actual name of his character. “I’ve seen lots of names thrown around,” says Broussard. “No one has quite picked the name that we’ve chosen for him. It would be fun to conceal that, if we can.”
